我使用homebrew install python 2.7.10并且usr/local/bin/python
链接到python 2.7.10。但是当我运行我的python代码时,会发生如下异常。但是当我使用IPython导入numpy时它很顺利。
当我使用python它告诉我/usr/local/bin/python
的命令时,使用whereis是python它告诉我那是/usr/bin/python
。

尝试将Python从2.7.10降级到2.7.9,例如:
brew switch python 2.7.9
通过覆盖现有的,因为2.7.10似乎存在一些特殊问题。
对于conda,请尝试:conda install python=2.7.9
(根据this)。
如果PYTHONPATH
变量未在任何地方被覆盖,请仔细检查。
或者考虑使用Python 3。
